Comparative Study
To What Extent Are Main Accident-Insurer Cases Representative of All Significantly Injured? A Swiss Monocenter Perspective.
Background and Objectives.-Even though Switzerland has a compulsory insurance system, there is a lack of detailed information on the treatment and outcome following trauma. The objective of this evaluation was to examine to what extent cases insured by the largest accident-insurer (Suva) are representative of all significantly injured. Methods.-Trauma center analysis of all ≥16 year old trauma patients with a New Injury Severity Score (NISS) ≥8, comparing the characteristics of Suva- vs non-Suva cases (chi-square; univariate explained variance R2; multivariate logistic regression analysis, Nagelkerke R2). ⋯ Conclusions.-Significantly injured patients in Switzerland may be considered comparable from a statistical point of view whether insured by the main accident-insurer or not, provided groups are adequately controlled for age and gender. Other differences appear to be only marginal. Respecting these limitations such data can justifiably be given as Swiss reference statistics and the relevant insurer outcome information used for international comparison.

Background and Importance.-Globally, almost one million new cases of stomach cancer were estimated to have occurred in 2012 (952,000 cases, 6.8% of the total), making it the fifth most common malignancy in the world, after lung, breast, colorectal, and prostate. Gastric cancer was the world's third leading cause of cancer mortality in 2012, responsible for 723,000 deaths, 8.8% of total cancer deaths. 1 In 2017, 28,000 new cases and 10,960 deaths are estimated for gastric cancer in the United States. 2 Estimated United States prevalence counts on January 1, 2014, for patients diagnosed within the previous 5-years was 48,271 (SEER Cancer Statistics Review-2014). Prognostic indices of survival & mortality in patients with gastric cancer are related to tumor stage including nodal involvement, direct tumor extension beyond the gastric wall, and wide-spread dissemination. ⋯ Mortality is a function of incidence and survival, and unfortunately, almost all of this decrease is due to the decrease in incidence of stomach cancer. Of the 157,258 invasive cases, 86.6% were clinically staged and 76.8% were histologically graded. Conclusions.-Given the histologic and etiologic heterogeneity of gastric cancer, major improvements in mortality and survival outcomes await the development of diagnostic markers for earlier diagnosis, and genomic sequencing and identification of chromosomal aberrations, nucleotide substitutions and epigenetic modifications that drive malignant transformation, for the development of targeted therapies for almost 200 gastric cancer subtypes.

-The values of SEER site recode variables are based on the primary site and histology data fields submitted to SEER by the registries. The site recode variables define the major cancer site/histology groups that are commonly used in the reporting of cancer incidence data and are added to the SEER databases as a convenience for researchers. These codes and definitions are periodically updated and changed by the National Cancer Institute as newer and more applicable information becomes available. Because this myeloma analysis includes cases diagnosed 2010+, the ICD-O-3 recode-updates with adjustment for WHO 2008 hematopoietic histologies that account for changes in the obsolete classification of hematopoietic histology codes, and the assignment of new names (ie, multiple myeloma-MM - to - plasma cell myeloma-PCM) is adhered to and used here. Plasma cell myeloma (PCM) is a bone-marrow based multifocal plasma cell malignancy (primary site C421). PCM is characterized by a single clone of plasma cells, believed to be derived from lymphoid B cells, and spans a clinical spectrum from asymptomatic to aggressive forms, plus disorders caused by the deposition of abnormal immunoglobulin chains in tissue. The current myeloma group ICD-O-3 histologic morphology types consists of: ICD-O-3 9731: Plasmacytoma, NOS, occurring in bone (osseous plasmacytoma malignancy data reportable to SEER only beginning since 1986); ICD-O-3 9732: Plasma cell myeloma - composed of three clinical variants: a) asymptomatic, b) Non-secretory myeloma, and c) Plasma cell leukemia (all coded to 9732); ICD-O-3 9734: Extramedullary plasmacytoma; anatomic sites other than bone. ⋯ -Recent SEER age-adjusted incidence trends, 2011-2014, for all races has been downward, with an annual percentage change (APC) of -2.5% per year. Mean age in plasma cell myeloma (PCM) patients was about 1-year less in males (67.8 yrs) than in females (69.2 yrs). PCM is accompanied by a very high excess mortality and much reduced 5-year relative survival ratio especially in older age groups. Generally, first year excess death rates (EDRs) decreased with duration but increased with advancing entry age, and there was no sex difference. First year EDRs in blacks, all ages combined, was quite high but lower than EDRs in whites. Median survival, actual survival and 5-year relative survival ratios diminished precipitously to extremely low levels with increasing entry age attesting to the lethal character of this disease especially in older patients.

-Incidence and prognosis of cancers of the endocrine glands vary greatly by stage and histologic type, and, thyroid cancer accounts for most (92%) of the cancers of the endocrine glands. It is the 8th most common of cancers and has been rising in incidence since 1975. It remains a formidable health threat in the United States in 2016 with estimated cases of 64,300 and 1980 deaths. ⋯ - Tables 1 - 8 provide basic SEER epidemiologic, demographic, case-statistics, and comparative mortality follow-up data of 4 principal and 2 supplementary thyroid cancer oncotypes by age, sex, race, stage and disease duration of patients in the 1993-2013 time-period. [Table: see text] [Table: see text] [Table: see text] [Table: see text] [Table: see text] [Table: see text] [Table: see text] [Table: see text] Conclusions.-Thyroid cancer when localized has a very good prognosis, with no significant excess mortality after diagnosis in papillary and papillary follicular variant cancers (PFV). Because nearly two thirds of thyroid cancers are localized, and excess death rate (EDR) is small in patients with regional cancer under age 50, overall excess mortality for all ages also virtually disappeared after 10 years in papillary and follicular cancer. Overall, the 5-year survival rate is greater than 90% for papillary and follicular carcinomas. Nevertheless, because of the marked predominance of papillary carcinoma, the continued increase in its relative frequency and annual projected deaths, thyroid carcinoma remains a significant health concern in the current era.

Neuromyelitis optica (NMO) is an uncommon central nervous system demyelinating disease that produces transverse myelitis and optic neuritis. Although commonly misdiagnosed as multiple sclerosis, a number of features can help differentiate the two entities, including the presence of NMO-IgG. Immunosuppressants are used to treat NMO, but the overall prognosis is poor.
